Analysis of Multi Dimensional Codes for OCDMA System
Abstract
The wide-ranging services of the Internet have caused the rapid increase of bandwidth requirements on the access networ that can be achieved by relying on fiber optics for future networks. OCDMA is a technology to realize multiplexing transmission and multiple access by coding in the optical domain, supporting multiple simultaneous transmissions in the same timeslot, space and frequency. It is another technology of multiplexing and multiple access. Performance of OCDMA is based on coding techniques. Through this communication various codes for these networks proposed by researchers are discussed like zero cross correlation codes, Perfect Difference Code Set based , optical orthogonal codes, Quasi optical orthogonal codes ,Constant Weight Symmetric OOC, Constant Weight Asymmetric OOC, Variable Weight OOC, Prime Codes, Modified Prime Codes, Time Spreading codes , Frequency Hopping Codes, Linear Congruence codes, Quadratic Congruence codes, Extended Quadratic Congruence codes, Bipolar Codes , Costas Arrays e.t.c and the codes proposed by authors based on two models A and B .Based on their methodology comparison thereof is drawn that the codes given by researchers are easy to construct and have good properties.
